Hey, I have a situation with a working postfix install which I am not sure how to implement.
the main problem is that from time to time I get a "rejected" mail from a remote system and which I cannot do a thing about. the setup is like this: Local client(sasl) ->(submission 587)Local POSTFIX the local postfix hosts one\two virtual domains. the postfix uses an amavisd-new for mail filtering. The setup works fine and the local POSTFIX is setup with: smtp sasl auth using a relayhost. I have a faileover relayhost in postfix but I want another thing. I want to define that all local\virtual domains will be delivered to the dovecot mailer. and specific outgoing domains will be relayed using specific relay servers while all other traffic will be relayed using the relayhost or failover relayhost. the current postfix config is: # cat main.cf |grep -v ^#|grep -v '^$' queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix mail_owner = postfix myhostname = mail.example.com inet_interfaces = all inet_protocols = all mydestination = $myhostname, localhost.$mydomain, www1 unknown_local_recipient_reject_code = 550 alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /usr/sbin/sendmail.postfix newaliases_path = /usr/bin/newaliases.postfix mailq_path = /usr/bin/mailq.postfix setgid_group = postdrop html_directory = no manpage_directory = /usr/share/man sample_directory = /usr/share/doc/postfix-2.6.6/samples readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES home_mailbox = .maildir/ virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf local_transport = dovecot virtual_transport = dovecot dovecot_destination_recipient_limit = 1 smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_unknown_sender_domain, check_policy_service unix:private/policy, check_client_access hash:/etc/postfix/rbl_override reject_rbl_client bl.spamcop.net, reject_rbl_client sbl.spamhaus.org, smtpd_sender_restrictions = permit_sasl_authenticated, permit_mynetworks, check_sender_access mysql:/etc/postfix/mysql-block-virtual-domains.cf reject_invalid_helo_hostname, reject_non_fqdn_sender, warn_if_reject, permit mynetworks_style = host smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/saslpass smtpd_sasl_local_domain = $myorigin smtp_sasl_security_options = smtp_sasl_tls_security_options = noanonymous relayhost = [smtp.012.net.il] smtp_fallback_relay = [mail.example1.com]:25 smtpd_tls_cert_file = /etc/ssl/ssl.crt smtpd_tls_key_file = /etc/ssl/ssl.key smtpd_tls_security_level = may smtpd_tls_CAfile = /etc/ssl/dca.pem biff = no empty_address_recipient = MAILER-DAEMON queue_minfree = 120000000 content_filter=amavisfeed:[127.0.0.1]:10024 policy_time_limit = 3600 message_size_limit = 20480000 the master.cf is: # cat master.cf # # Postfix master process configuration file.
